ABRAHAM M. FORRESTER, OF RACINE, VVISUONSIN.

HARROW-TOOTH.

SPECIFICATION forming part of Letters Patent No. 267,069, dated November'7, 1882.

Application filed April 2l, 1882. (No model.)

To all whom itmay concern Beit known that I, ABRAHAM M. FORREST- ER, ot'Racine, n the county of Racine, and iu the State ot' Wisconsin, haveinvented certain new and useful Improvements in Harrow- Teeth; andI dohereby declare that the following is a full, clear, and exactdescription thereof.

M y invention relates to barrow-teeth; and it consists in a novel methodof attaching them to their supportingbeams and adj nsting them withrelation thereto.

In the drawings, Figure 1 is a side View of a section ot' a harrow-beamwith my improved tooth attached, showing a side view of the lat ter; andFig. 2 is a cross-section ot'a harrowheam with my improved toothattached, and showing an edge view of the latter.

A is the beam, and B is the head, to which the tooth C is hung. Thishead has an upper serrated flange, b, that rests against the un-A derside ot' the beam, and is clamped to it by a bolt, B', that passesthrough the tlanges b and the beam, a nut, D, and washer d serving todraw it tight. The head B is made tapering about its vertical center toits lower end, and is provided with four squared openings, E E' E2 E3,(the latter near its eXtreme lower end,) to receive the bolts F F', thatclamp the tooth to it. round holes, one in its extreme upper end and theother just the distance below it that the opening E3 istrom openingsE,E', and E2. The

. tooth C has a sharp edge and blunt back, and

The tooth is provided with twol a point that tapers from its rear to itsfront. In Fig. 1 the tooth is shown in position for tearing 'up landthat is full of small roots, and when it is in this position the upperbolt, F, is passed through the opening E2 in the head, and thereforeholds the tooth in position to when it is desired merely to stir uplight soil the tooth is carried to a vertical and the bolt F passedthrough the opening E'. If, however, the soil is to be merely dragged,the bolt F may be passed through the opening E, and the tooth will thenmerely drag through the soil; and to meet other contingencies I can,after loosening the nut on bolt B', turn the head B to the right orleft, so as to correspondingly incline the knife or tooth, orI may turnthe head entirely around, so as to bring the back ot' the knife inposition to take the soil, and in every case I secure the head in itsposition by'screwing up the nnt I) or bolt B'.

What I claim as my invention, and desire to secure by Letters Patent, is

The angular bracket B, having serrated head b, pivotal perforation E3,and the series ot' apertures E E' E2, in combination with the swordtoothC and bolt B', as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, onthis Sth day of April, 1882, in the presence of two witnesses.
